"It's Now or Never" is a song recorded by Elvis Presley and released as a single in 1960. The song is one of the best-selling singles by Presley (20 million copies), and one of the best selling physical singles of all time, In 1960, "It's Now or Never" was a number-one record in the U.S. for Elvis Presley, spending five weeks at number one.
"It's Now or Never" is one of two popular songs based on the Italian song of the Neapolitan language, O Sole mio, the other being "There's No Tomorrow," recorded by US singer Tony Martin in 1949, which inspired Presley's version. In the late 1950s, while stationed in Germany with the US Army, Presley heard Martin's recording. It is also likely that he was inspired to record this because of his fondness for Mario Lanza who had first popularized "'O Sole Mio" to American audiences and who had died the year before
